“You could even put this stadium to attract 100,000 people to come in right in the middle of the zone and there was no problem [according to the mayor],” said a sarcastic Silver, who infuriated the mayor two years ago when he helped kill the stadium project.

Silver, who has the power to single-handedly kill the new traffic plan, also questioned Bloomberg’s contention that congestion pricing is needed to help alleviate asthma and other health problems.

While noting something needs to be done to improve the environment, Silver argued that many areas with high childhood-asthma rates, such as the South Bronx, Bedford-Stuyvesant and Harlem, are not within Manhattan’s congestion-pricing district.

“In fact, some of those areas will become parking lots for the people driving around the neighborhoods looking for parking spots in order to avoid the congestion-pricing fees,” Silver said.

The speaker also reiterated a host of past concerns, including whether the mass-transit system can handle the additional ridership and fears of having 1,000 cameras on city streets to monitor vehicles in the congestion zone.

“There is a plan that could be put together that can obviously alleviate the environmental negativism of what takes place in Manhattan right now – with or without [congestion pricing],” Silver said.

Despite his criticisms, though, Silver added that it’s “very possible” a plan can be agreed to by an August federal deadline for special transportation funding.

The Assembly, which heard testimony from Bloomberg on the issue at a hearing last week, has another one scheduled Friday.

“Once we get all the facts out there, we’ll be in a better position to make some recommendations,” Silver said.
